Yes, as always one must choose the correct gear for the specific needs.
Perhaps more importantly, even the toughest ones can only go down to 30-40 ft. That may be plenty for snorkling, but nowhere near enough for scuba-diving.
I take my little guy on almost every dive because most of the dives in my local area max out around 14m ish (40ish feet). In many places vacation divers in particular go, this is pretty normal and it's often where most of the action is!
I also took it along on my deeper dives in Bonaire because I wanted stuff at the beginning/end of the dive and getting in and out - didn't try to take photos at depth as I know from experience that it doesn't actually like shooting at 14m but it didn't hurt it (OK, in reality, I totally forgot I had it with me coz I was going to test it out LOL).
If you're gonna dive a lot or dive deep or want to expand your system etc - housing a good compact, 3/4 or dslr is the way to go.
If you're going to putter on holidays and/or want a romper of a camera that's happy with pretty much anything you throw at it & that you don't have to spend much time futzing with, then I'd suggest not fooling with a housing.
just my own two cents from my own experiences - advice on the internet is worth what you pay for it sometimes
